About Us

We are a group of domestic and international non profit organizations working in Canada to reduce oil and gas methane emissions through rigorous science, policy, advocacy and legal expertise. Collectively, we represent millions of members across North America calling on global action to tackle methane emissions from the oil and gas industry.


David Suzuki Foundation

The David Suzuki Foundation is a leading Canadian environmental non-profit organization, founded in 1990. We operate in English and French, with offices in Vancouver, Toronto and Montreal. We collaborate with all people in Canada, including First Nations leadership and communities, governments, businesses and individuals to find solutions to create a sustainable Canada through scientific research, traditional ecological knowledge, communications and public engagement, and innovative policy and legal solutions. Our mission is to protect nature’s diversity and the well-being of all life, now and for the future

Pembina Institute

The Pembina Institute is working to solve today’s greatest energy challenges – reducing the harmful impacts of fossil fuels while supporting the transition to an energy system that is clean, safe and sustains a high quality of life. We provide our expertise to industry and government leaders, and we advocate for a strong, science-based approach to policy, regulation, environmental protection, and energy development.

Amanda Bryant

Senior Analyst

Amanda is a senior analyst with the Pembina Institute’s oil and gas program, based in Calgary. Her focus is on developing and advocating for evidence-based policy solutions for oil and gas methane emissions.

Amanda began her methane journey as a policy researcher and writer at St. Francis Xavier University’s FluxLab – one of Canada’s foremost methane measurement labs. There, she worked to bring a policy dimension to the lab’s measurement work. She researched and wrote topical op-eds on subjects such as the connection between methane and air quality, the importance of harmonizing air quality and methane regulations, innovative and rapid policy developments in the U.S., climate disclosure reporting requirements, methane intensity, and natural gas certification. She then built on her foundation of methane policy knowledge as a consultant at the Pembina Institute before joining as a full-time employee.

She has a PhD in Philosophy from the City University of New York Graduate Center, and she received her MA from Simon Fraser University. In her spare time, you can find her jogging, watching Star Trek, or playing video games.
